In a tither

[Lyne__0__0]

  Several years ago I was diagonist as having MS. I have been to Mayo's and
  they could not come to a conclusion as to what I have.  My new doctor has
  come up with an idea that I may have something he called cerebellarpathy.
  I have no idea of what that may be.  Cerebellar Ataxia is as close to some
  of the symptoms I have.  Alot of the symptoms  I have are like MS,and yet
  they aren't.  No one can explain why my feet are not only numb, but that
  I can barely move my toes. Last year I had a bad time in the summer. I was
  not able to walk and used my wheelchair to get to the bathroom. I was bed
  ridden for two months. I went to see another doctor who specialized in
  sports injuries, thinking that maybe I had a pinched nerve in my back and
  that I had been diagonist wrong from the beginning.  He orded a MRI and it
  came back negative. No pinched nerves. But he did notice that I have had
  muscle damage on my leg. Damage he said that was irreversabal. So I have
  holes above my knees and a portion of my thigh muscle gone. I would like
  to know if any of these things are in anyway related to Cerebellar Ataxia

I'm not quite sure what you mean be "holes above the knees" and "muscle damage in the leg" but this doesn't sound like multiple sclerosis or cerebellar syndromes.  Cerebellar disorders cause a breakdown in the smooth movements of the arms and legs and can cause unsteadiness of gait (ataxia), a misjudgement of distance in reaching for objects (dysmetria), slurring of speech, and tremor.  But note that many diseases involve other systems along with the cerebellum - While a tumor or infectious colllection may just involve the cerebellum, other disorders e.g. multiple sclerosis can affect vision, strength and sensation.  The numbness in your feet could be caused by MS but the changes in your muscle would not.  Some disorders that involve the cerebellum involve the spine and even the peripheral nerves - many disorders in fact ranging from Vitamin E deifiency to hereditary disorders called the Spinocerebellar Ataxias (of which there are many type).  In disorders like this, not only would people get hte cerebellar problems above but could also get numbness in the feet from spinal or peripheral nerve problems.  Again, not sure about the muscle problem you describe unless there's atrophy and muscle loss there - if so, again this could be from involvement of the peripheral nerves or roots but not purely from the cerebellum.
Hope this was of some help.
